MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent N 0. 467,089, dated January 12, 1892.

Application filed January 3, 1891. Serial No. 376,682. (No model.)

To all whom it may concern:

Be it known that I, HORACE B. FORBES, of Ogden, in the county of Weber and Territory of Utah, have invented a new and useful Improvement in Magazine Fire-Arms, of which the following is a full, clear, and exact description.

My invention relates to an improvement in magazine fire-arms, and has for its object to provide a means whereby during the rearward and forward movement of the hammer the carrier-block will revolve sufficiently to place a cartridge in position to be fired, receive a cartridge from the magazine, and expel the shell of the cartridge last fired.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a partial side elevation and a partial sectional view of a fire-arm embody ing my improvements; and Fig. 2 is avertical section taken, practically, on the line a; of Fig. 1. Fig. 3 is a vertical section of a portion of the breech and stock of a fire-arm embodying my improvement, illustrating the method of revolving the cylinder.

The receiver is of circular form, abarrel ll being secured in its forward end in the usual manner, and the receiver is preferably provided at the breech with a block 12, screwed or otherwise secured therein, whereby the carrier-block A may be introduced into the receiver. The receiver at its forward end, below the barrel, is provided with an aperture 13, extending into the interior, and one end of a magazine-tube 14 is inserted in the aperture, as shown in Fig. 1, the'said tube being supported beneath the barrel by means of straps 15 or their equivalents.

The cartridges 16 may be introduced into the magazine in any approved manner-as, forinstance, at one sideand within the magazine, at or near its outer end, a spring 17 is secured, the said spring being attached to the cartridge-follower 18.

The cartridges adapted for use in connection with the improved arm are provided with a cap 19, of less diameter than the diameter of the shell, whereby the cap forms, essentially, a central offset at the bottom of the shell. The cartridges are held within the magazine until required for use by a stop 20, which stop is in the form of an angle-lever pivoted in a recess in the forward end of the receiver below the aperture 13. The upper member of the stop is adapted to normally engage with the bottom of the inner shell of the magazine at the peripheral surface thereof, as shown in Fig. '1, and the other member of the stop is connected by a link 21 or its equivalent with the trigger 22. The trigger and hammer are so constructed that when the trigger is manipulated the hammer will be thrown backward and then carried forward to fire the cartridge. Such construction is well known and needs no description, coustituting no portion of the invention.

\Vithin the receiverthe carrier-block A is held to revolve. The said block comprises a central section 23, through which a pivot-pin 24 passes, the ends of the pin being pivoted in the ends of the receiver, and arms 25, preferably four in number, arranged at equidistance apart and extending at a right angle from the sides of the central section, as is best shown in Fig. 2. The carrier-block is revolved upon the movement of the trigger 22 in the same manner that the carrier-blocks of revolvers are rotated.

One method of revolving a carrier-block by the movement of the trigger 22 is illustrated in Fig. 3, in which it will be observed that the carrier-block is provided at its butt with centrally-located ratchet-teeth 34, circularly arranged. The trigger 22 carries two dogs and 36, the dog 35 being longer than the dog 36 and adapted for engagement with the ratchet-teeth 3i of the carrier. Both dogs 35 and 36 are preferably pivotally connected with the trigger at its upper rear end, and the dog 36 is normally held in a rearward position by a spring 37.

The upper rear end of the -\Vhen the trigger is pulled back, the dog 35 dog 36 is preferably cylindric, and said dog 36 is adapted for engagement with the hammer of the gun. The hammer is provided with a nose 38 and a spur 39 beneath the nose, and the lower end of the hammer is ordinarily provided with a tongue 40, having a notch 41 in its under face near its extremity, and beneath the tongue of the hammer a springpressed pawl 42 is pivoted in the stock, and a spring-pressed stop-plate 4:3 is carried by the forward arm of the trigger, adapted to prevent the carrier A from turning when the hammer is thrown downward by the trigger.

will revolve the receiver A the distance of one ratchet-tooth 34, and the dog 36, attached to the trigger, will force the hammer back. This action occurs when the trigger has been carried rearward about one-half its stroke. At the remainder of the stroke the dog 36 passes the spur 39 of the hammer and releases the hammer. Thereupon the said hammer, being spring-pressed, is forced to its firing position. When it is desired to lock the hammer backward, it is carried back by hand, and the rear spur of the pivoted pawl 42 enters the notch 41 in the tongue 40 of the hammer, and when so locked, when the trigger is brought back to fire a charge, it will engage with the front horn or member of the pawl 42 and disengage it from the hammer, permitting the hammerspring to act to throw its needle in engagement with a cartridge presented to be fired.

In one side of the receiver a longitudinal opening 26 is located, the said opening being slightly longer than the length of the cartridges to be fired. The outer faces of the arms are cylindrical, and each arm is constructed in two sections a and a, the section a being integral with the central portion of the block and the section a hinged thereto. The inner faces of both sections a and a at their peripheries are rabbeted, whereby when one is closed upon the other a Inortise joint or connection is obtained, as illustrated in Fig. 2.

Each arm is provided with a cartridge-cell 27, which is formed partially in each section, and in the wall of each cell formed by the fixed section alongitudinal channel 28is produced, and in the channel one end of a spring 29 is rigidly fastened, the other end, which faces the breech, being free. The width and thickness of the spring corresponds to the depth and width of the channel, so that when a cartridge is placed in the cell it forces the spring inward until its outer face is within the radius of the circle of the cell. The guardplate 30, which is attached to the stock and the receiver, is preferably made semicircular in cross-section.

In operation when the trigger is manipulated and while the hammeris passing backward and forward, the carrier-block is rotated so as to bring a cartridge in front of the bore of the barrel, and the arm carrying the shell of the cartridge last fired is at that time brought opposite the opening 26 in the receiver,whereupon the hinged section of the arm drops by gravity and the spring 29, being released from pressure, acts to force the shell out from the cell through the said opening in the receiver, and as the shell is being extracted the lower cell is opposite the inner end of the magazine and as the stop 20 is disengaged from the cartridge in the magazinc is forced by the follower 18 into the said cell. The shell is fired by the pin 31 of the hammer striking the cap 19, or the firing may be effected in any other suitable or approved manner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
